Start your bitcoin dev journey with bitcoin transactions, scripts, and SegWit
What you'll learn
Basic intro to encodings, endianness, and bitcoin's specific base58 encoding
Learn the components of a bitcoin transaction
How to parse a bitcoin transaction from bytes
Intro to bitcoin Script, including writing your own bitcoin locking scripts
How to write standard bitcoin locking scripts (P2SH)
How SegWit changed the basic bitcoin transaction
The standard SegWit locking script: P2WSH
How to make legacy compatible SegWit scripts: P2SH-P2WSH
Requirements
This course is open to everyone, but it is in-depth bitcoin transaction protocol content.
Developers that have experience with byte-formats, encodings, and bitcoin will likely find it more approachable
Description
So you've heard about bitcoin? Ever wondered what's going on with the data in a transaction, or how bitcoin gets locked up and transferred from one holder to another?This course by Base58 instructor niftynei, will take you on a deep dive of the fields, bytes, and scripts that make up the bitcoin blockchain data. In an software engineer focused manner, we'll go over everything you need to know to build your own bitcoin transaction parser, write your very own custom bitcoin locking scripts, and adapt your transactions to the modern SegWit format.Step 1: Intro to bitcoin transactionsWe'll start off learning about what a bitcoin transaction is. Specifically, what fields do they contain? We learn how to calculate a transaction id and what transaction fees are, and how are they calculated. Finally, we'll talk about coinbases and block rewards.Topics: transaction fields, endianness, transaction ids, fees + transaction weights, coinbasesStep 2: Enter ScriptIn week two we start talking about Bitcoin's native "programming language": Script! We'll write our own script this week (and learn about hashes and preimages). Once we've written a script we'll try locking some bitcoins up to it, as well as unlocking them.Topics: Script, standard scripts, P2SH, opcodesStep 3: Transacting with SegWitNow that we've seen how transactions are constructed and built, we'll introduce the bitcoin omnibus update bill, the SegWit soft-fork. SegWit impacted the structure of a transaction and its fee calculations, so we'll dive into how these updates work and two of the 'new' SegWit script types: P2WSH and P2SH-P2WSH.Topics: SegWit! P2WSH, P2SH-P2WSH
